Abstract BACKGROUND AND IMPORTANCE: This technical note describes a complication related to the use of the Merci embolectomy device not previously reported. The device can induce critical flow limitation within an accessed vessel because of a combination of vasospasm and anatomic conformational changes. Furthermore, this can limit the safe removal of the device from intracranial vasculature. We present a novel rescue technique that can be used to safely retrieve the entrapped Merci device without inciting localized vessel injury. CLINICAL PRESENTATION: A 51-year-old male with embolic occlusion of the distal basilar artery and dissection-related occlusion of the left cervical vertebral underwent mechanical thrombolysis. Flow-limiting vasospasm and/or anatomic conformational changes/ telescoping of the intracranial right vertebral artery segment was induced during deployment with subsequent entrapment of the device. Reclamation of the entrapped device was performed by initially removing the Merci microcatheter. The entrapped and fixated device was then resheathed into a 4F slip catheter within the intracranial vertebral artery. The Merci device and the slip catheter were then removed. Right vertebral and proximal basilar artery flow was reestablished after removal of the Merci device. Successful clot extraction was thereafter performed using a microsnare. CONCLUSION: In vitro assessment of the device has demonstrated its propensity to induce vasospasm. In vivo entrapment of the device has not been previously reported. Successful retrieval can be achieved if the Merci device becomes entrapped and fixated. This may be an important consideration as increased utilization of the device occurs.

Background Distal landing zone accuracy is critical in some intracranial aneurysms treated with the Pipeline Embolization Device (PED), and delayed opening of the distal end of the device can complicate the procedure. Here, we report a technical nuance that facilitates accurate placement of the distal end of the PED by ex-vivo, pre-implantation release of the PED Flex polytetrafluoroethylene (PTFE) sleeves. Technical note The PED Flex is partially pushed out of the introducer sheath ex-vivo, pre-implantation until the distal PED opens entirely and the PTFE sleeves are located distal to the device. Without inverting the PTFE sleeves, the PED is carefully pulled back into the introducer sheath placing the PTFE sleeves inside the device. The PED is loaded into the microcatheter and advanced toward the site of implantation. When the PED is initially deployed and pushed out of the microcatheter, it opens immediately and provides an anchor for the remainder of the deployment process. We present a video (supplementary material) that illustrates the technique along with an illustrative case. Conclusion Ex-vivo, pre-implantation release of the PTFE sleeves is an option in aneurysm treatment where distal landing accuracy is critical. Even without the protection of the PTFE sleeves, our clinical observation shows that the PED can be advanced safely through the microcatheter in selected cases.
